fix(distro): correct install recipes — all 5 binaries, install-full for frontend

distro::install now explicitly builds vapora-backend, vapora-agents,
  vapora-mcp-server, vapora-a2a, and vapora-cli in one cargo pass.
  vapora-a2a and vapora-mcp-server were missing from the build command;
  vapora-a2a was absent from the copy list entirely.

  Replaces the broken UI=true parameter with a separate install-full recipe
  that depends on install and runs trunk --release. just 1.x treats KEY=value
  tokens as positional args to the first recipe parameter when invoked via
  module syntax (distro::recipe), not as named overrides.

  install-targets now includes wasm32-unknown-unknown with an idempotent check.
  build-all-targets excludes wasm32 from the workspace loop to avoid failures
  on crates that don't support WASM.

 ### Fixed - `distro.just` build and installation
 
 - `distro::install`: now builds all 5 server binaries in one `cargo build --release` pass
-  - Added `vapora-a2a` and `vapora-mcp-server` to the explicit build list (were missing; copied from stale `target/release/` if present)
+  - Added `vapora-a2a` and `vapora-mcp-server` to the explicit build list (were missing; silently copied from stale `target/release/` if present, skipped otherwise)
-  - Added `vapora-a2a` binary to the install copy list (was absent entirely)
+  - Added `vapora-a2a` to the install copy list (was absent entirely)
-  - Added `UI=true` optional parameter: runs `trunk build --release` before copying; validates `trunk` is available first
+  - Missing binary → explicit warning with count; exits non-zero if zero installed
-  - Missing binary → explicit warning with count instead of silent skip; exits non-zero if zero installed
+- `distro::install-full`: new recipe — runs `install` as a dependency then `trunk build --release`
-- `distro::install-targets`: added `wasm32-unknown-unknown`; changed to idempotent check (`rustup target list --installed`) before calling `rustup target add`
+  - Replaces the broken `UI=true` parameter approach: `just` 1.x treats `KEY=value` tokens as positional args to the first parameter when invoked via module syntax (`distro::recipe`), not as named overrides
-- `distro::build-all-targets`: explicitly excludes `wasm32-unknown-unknown` from the workspace loop (WASM requires per-crate build via `trunk`; the loop would fail on non-WASM crates)
+  - Validates `trunk` is in PATH before attempting the build
+- `distro::install-targets`: added `wasm32-unknown-unknown`; idempotent — checks `rustup target list --installed` before calling `rustup target add`
+- `distro::build-all-targets`: excludes `wasm32-unknown-unknown` from the workspace loop; WASM requires per-crate `trunk` build, not `cargo build --workspace --target wasm32`
